盐碱地的治理与利用

Analysis of control and use of alkaline soil

为了解决我国盐碱地对农业土地资源和农业生产发展的危害,采用理论分析与物理及生物治理并开发利用盐碱地的方法,揭示出盐碱地的一般成因以及盐碱土对绿色植物乃至农业生产的危害。通过对盐碱地的治理与利用,可以逐渐地使土壤盐碱得到控制和改良,从而使我国农业土地利用率得到提高。合理地改良和利用盐碱化土壤,因地制宜,采取切实可行的改良措施,就可以将这部分可观的后备资源,转变为宝贵的土地资源,提高耕地面积,扩大农业生产,为我国农业可持续发展奠定基础。

In order to solve the harms to the agriculture land resources and the development of agricultural industry by the alkaline soil,this paper gives a theoretical analysis with physical and biological control and and ways to develop and use the alkaline soil.It also indicates the common cause of formation of alkaline land and the harms to the green land and even the harms to the agricultural industry caused by alkaline soil.By controling and using alkaline soil,we can gradually improve the condition of alkaline soil,so as to raise the using rate of farm land in our country.By improving and using the alkaline soil properly,taking actions that suit local circumstances,we can transfer the considerable reserved resource into valuable land,and increase the area of agricultural acreage,and improve the agricultural industry so as to lay a strong foundation for the sustainable development of agricultural industry in our country.
